In Scotland in the 18th and 19th centuries, a person who made a living by doing odd jobs was called a cawdy or caddie. The word comes from the French word cadet, which came into English in the 17th century. The chief meaning of cadet in both French and English is “a student military officer.” The caddies formed organized groups, and it may be that the military structure of the group suggested the name. Some caddies lived near universities and took jobs working for students. Other caddies found jobs carrying golf clubs. As the popularity of the game grew, so did use of the term caddie for one who carries a golfer's clubs.
